Make mjml-processor java14+ compatible

robinjoerke commented 2 years ago

Hi, i wanted to use mjml-processor in a java17 project so i had to make some changes as nashorn is not published with java anymore starting with java 15. (was deprecated in java 11). I though a PR might be appreciated so here it is

Brief overview over the changes:

Update Gradle to Version 7.4.
Use openJDK nashorn version instead of deprecated version bundled in jdk. (this will break in java14+)
Propagate AssertionErrors in threaded test to main thread to assure propper handling by junit
Ignore Line endings in tests to make tests multiPlatform compatible
bump compatibility version to java 17
remove deprecated maven plugin

❤️ Thanks @robinjoerke . I can't merge it (anymore), but the PR is highly welcome. I guess you know how to use your updated version via jitpack?

I already published it to a local private maven repo for my usecase. taht version is completely build on maven instead of gradle. but i ported back the changes i made to the gradle based version to make it accessible to others. if you say there is no way this will be merged and published here i could set up a jitpack repo based on my fork. (never done that before but im sure i would be able to fiure it out)
